INKING ATTACHMENT FOR JOB-PRINTING PRESSES.

SPECIFICATION formngpart of Letters Patent No. 655,177, dated August 7,1900.

Application Aiea cette 24; 1,899. serian. 734,642. (Nomaden To all wwmit may concern:

Beit known that we, HARRY S. ADAMS and vCHARLES E. WILD, citizens of theUnited The object of the invention is to print in two dierent colors ofink at the same time; and the invention consists of two independentinking-disks provided with mechanism for rotating said disks.

The construction of the invention and its novel features will be fullydescribed hereinafter and defined in the appended claims, in connectionwith the accompanying drawing, which forms a part of this specification.

The drawing is a View in perspective of the under side of theinking-disks.

The reference-numeral1 designates a plate provided on its under sidewith a depending pin 2, adapted to fit the socket on a job (or platen)press, which ordinarily receives the central pivot-pin of the usualinking-disk. VIn rear of the pin 2 a bracket 3 depends from `the undersurface of the plate 1.

4. and 5 designate armsprojecting from the plate 1 on opposite sides ofthe pin 2. The inner endsof these arms are provided withclamping-brackets 6 and set-screws 7 to clamp the device to the press,and the outer ends of said arms' are formed with sleeves 8, adapted toreceive the central pivots 9 of the disks 10. Each of these disks 10 isprovided on its under side with an annular -depending iange 11, theedges of which are formed with inclined teeth 12.

To the rear side of the bracket 3 is secured a horizontal reciprocatingbar 13, formed with an elongated slot 14, through which extend thesecuringscrews 15. From each end of the bar 13 projects a stud 16, towhichis se.

cured a pawl or dog 17. A coil-spring 18 is interposedbetween one of thestuds 16 and the adjacent side of the bracket 3.

19 designates a bell-crank lever fulcrumed upon the bracket 3, thelongfarm of said lever being secured to a screw 20, projecting from thebar 13, while its short arm is formed with a curved finger 21, whichextends through an opening 22 in the short arm of a second bell-cranklever 23, fulcrumed upon a bracket 24, secured to the arm 4 of theplate. The long arm 25 of the lever 23 eX- tends down and is bent at itslower end to adapt it to be struck by a suitable contact device securedto a moving part of the job (or platen) press.

The operation of the mechanism as thus described is as follows: Thelever 25 when struck by the projection from the press oscillates thebell-crank lever 19, thus forcing thebar 13 to the left and imparting apartial rotation to the disks 10 by the contact therewith of the dogs17. This movement of the bar 13 extends the spring 18, and as soon asthe lever 25 is released the said spring retracts the bar 13 to itsfirst position. It will be apparent that these two disks are adapted toreceive different-colored ink and that with the proper rollerattachments two colors may be imprinted at the same time from a singleform of type, part of said form being inked from one of the disks andpart from the other.

While the mechanism which we show and describe is operative andpractical, other means may be resorted to for effecting a simultaneousstep-by-step rotation of the disks. Hence we would have it understoodthat we reserve the right to make all such changes and modifications asmay properly fall within the scope of the appended claims.

We claim- 1. The combination with a plate or support provided on itsunder side with a depending bracket; a reciprocating Abar supported uponsaid bracket; a bell-crank lever fulcrumed on said bracket; a leverforactuating said bellcrank lever to reciprocate said bar; aretracting-spring for the bar; rotating disks each provided with anannular toothed ring; and dogs on said bar for actuating said disks.

2. The combination with a plate or support provided, upon its undersurface, with a bracket; of a slotted bar; means for securing said barto the bracket; a'bell-crank lever fulcrumed `on the bracket andengaging with the bar; a finger to said lever; a second lever IOOengaging saidnger and adapted to reciprocate the bar; a,retracting-spring connected to said bar and bracket; rotating disks'mounted upon the plate or support; anlannular` toothed ring upon eachdisk; anda gravityl seated dog at each vend of said bar for engage- A'operating said bar and disks.
